IMPROVEMENT IN FIRE=PROOF BUILDINGS.

Specification forming part of Letters Patent No. 156.808, dated November 10, 1874; application tiled October 21, 1874. I

To all whom t may concern Be it known that I, HENRY MAURER, of the city, county, and State of New York, have invented a certain new and useful Improve- Inentin Fire-Proof Buildings, of which the following is a specification:

This invention is illustrated in the accompanying drawing, in which` Figure l 'represents a transverse section.

Fig. 2 is a longitudinal section.

Similar letters indicate corresponding parts.

This invention consists in the combination of two sets of hollow tiles with the ioor-beams of a building, one set of tiles being supported by tapering or wedge-shaped strips formed on or secured to the upper parts of the beams, whiletheother set of tiles rests upon similar strips formed on or secured to the lower portions of said beams; the ends of the tiles being beveled oli' to Ycorrespond to the tapering strip on the beams, each of said tiles being made of such length as tolspan the distance between the beams, and constructed so that their outer surface will be depressed below, or iush with, the end of the said beams, in such a manner thatone set of tiles forms the floor, and the other set the ceiling, in a building; and that between the tloor-tiles and the ceilingtiles an air-space is formed, which promotes ventilation, and adds to the security ot' the building. rIhe edges of the beams are protected by tiles, which are fastened to the same, and join the I'ioor-tiles and the ceiling-tiles.

In the drawing, the letters A A designate the oor-beams in a building. In the example shown these beams are of wood and to the sides of each of them are secured two sets of tapering strips, a a b 11, with their narrow edges pointi n g upward. The strips aa form the supports for the floor-tiles BB, while the strips yb b support the ceilingtiles GC. v rIhese tiles are, by preference, made hollow, and their ends are chamfered off to correspond to the bevels ot' the -strips a a b b, so that if said tiles are placed between the beams they will be supported by said tapering strips, the tiles B somewhat above, and the tiles @somewhat below, the lower edges of said beams. The edges of the beams above and below are protected by thin intermediate tiles D, which t between the tiles B and the tiles C, respectively, and which are fastened in position by cement, or by any'ot-her suitable means. Between the iioor-tiles B and the ceiling-tiles C are formed airspaces D, which promote ventilation, and increase the security of the building against ire. When wooden beams are used these airspaces protect said beams against decay.

My improvement is applicable to floors or ceilings with wooden or iron beams; :and it' iron beams are used, the beveled surfaces, which serve to support the tiles, are formed in the rolling-mill together with bodies of said beams.

If desired, the tiles B and C may be made arched, in order to increase their strength.

What I claim as new, and desire to secure by Letters Patent, is-

In combination with the joists A, having the projecting tapering strips or bearing-surfaces a b, the tiles B C, having their edge-surfaces constructed to correspond with the bearingsurt'ace a b, each of said tiles being formed to span the distance between the beams, all constructed substantially in the manner herein shown and described,for th'e purpose specified.

In testimony Ythat I claim the foregoing I have hereunto set my hand.

HENRY MAURER.
